Thomas Gillespie born in Virginia in 1785-any info

He married Susan Fleshman in Indiana in 1817 and had 10 children. The oldest, John married Mary Owen from Kentucky in 1840 in Indiana and they moved to Livingston County, Missouri in between 1851 and 1854. They had 10 children, one was my great grandmother on my mother's side. I know Thomas's grand parents came from the Grampian Hills in Scotland, nothing else.
